DocumentMCP has basic tool definitions with descriptions and input schemas, but falls short of production quality. All three tools have descriptions (10-100 chars) and visible schemas with typed parameters. However, descriptions are minimal (avg 65 chars vs baseline 194), lack context on WHEN to use tools, and omit error recovery guidance. Parameter descriptions are present but terse. No output schemas documented. Error handling exists (ValueError raised) but provides no recovery hints. Tool composition is reasonable (list/read/edit separation), but edit_document lacks idempotency guarantees and confirmation patterns for destructive operations.

• Expand tool descriptions to 100-200 chars. Add WHEN to use: 'Call this first to discover available documents before reading or editing.' Include what it returns and any prerequisites.
• Add destructiveHint annotation to edit_document and implement a dry-run parameter or confirmation step. Document that edits are irreversible and suggest calling read_doc_contents first to verify content.
• Document output schemas explicitly. E.g., 'Returns: list[str], array of document IDs' for list_documents; 'Returns: str, full document content' for read_doc_contents.
• Enhance error messages with recovery hints. Change 'Doc with id X not found' to 'Document "X" not found. Available documents: [list]. Call list_documents() to see all.'
• Add parameter constraints to descriptions. E.g., 'old_str (string, case-sensitive, must match exactly including whitespace). Tip: call read_doc_contents first to copy the exact text to replace.'
